Bosch Rexroth HDS03.2-W075N-HS12-01-FW Servo Drive

Bosch Rexroth Indramat HDS03.2-W075N-HS12-01-FW is a drive controller in the HDS DIAX04 servo drive family, designed to command and amplify servo motors in high-precision motion systems. The R911190008 part number corresponds to this model and supports a SERCOS command interface plus an analog input for seamless mode transitions driven by control voltages. The unit is air-cooled with an internal fan and is rated for 75 A continuous output, delivering up to 0–500 VAC to servo motors with a control/update rate up to 1,000 Hz. The high-voltage DC bus input typically ranges from 530 to 670 VDC, with typical input current around 37 A, making it suitable for demanding automation environments that require synchronized multi-axis motion. Common applications include precision CNC, robotics, packaging, and automated manufacturing setups where tight synchronization and fast response are essential, and where Indramat DIAX04 drives are used as the drive controller stage.
